Is it toxic to go through your partner's DMs without their consent? Yes, but only if you find nothing. On a popular Reddit thread in the Today I F*cked Up Subreddit, a woman digs through her partner's DMs and actually finds some suspect messages.
TIFU by opening my fiancé's dms
The wound is still fresh, so bear with me.
I had a rough day, and my fiancé's algorithms are top-notch, so I was scrolling through his apps to entertain myself,f hoping for a pick-me-up. He went to take a shower. I opened his Instagram and noticed he had a couple of new DMs. We don't snoop through each other's phones, but we don't hide anything either (or so I thought), so I clicked on them to see if they were important because he doesn't check Insta that often.
